We pick k.root-servers.net, one of the 13 root servers (1), and ask it about mgoguen.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that mgoguen.com is delegated to two name servers, including ns7.zoneedit.com (3), so we ask that one and get the following answer:
Mgoguen.com is a domain controlled by two domain name servers at zoneedit.com. Both are on different IP networks. Incoming mail for mgoguen.com is handled by seven mail servers at googlemail.com and google.com having a total of 53 IP numbers. There are 33 duplicated IP numbers. Some of them are on the same IP network.
The two name servers ns3 and ns9.zoneedit.com together
More than one in eight of the several thousand of domains that use name server group 1 point to the two IP numbers 69.72.142.98 and 216.98.141.250 together (example: marcoyuen.com ).
